Orientation Invariant Ecg-Based Stethoscope Tracking For Heart Auscultation Training On Augmented Standardized Patients, Nahom Kidane, Salim Chemlal, Jiang Li, Frederic D. Mckenzie, Tom Hubbard

Computational Modeling & Simulation Engineering Faculty Publications

Auscultation, the act of listening to the heart and lung sounds, can reveal substantial information about patients’ health and other cardiac-related problems; therefore, competent training can be a key for accurate and reliable diagnosis. Standardized patients (SPs), who are healthy individuals trained to portray real patients, have been extensively used for such training and other medical teaching techniques; however, the range of symptoms and conditions they can simulate remains limited since they are only patient actors. In this work, we describe a novel tracking method for placing virtual symptoms in correct auscultation areas based on recorded ECG signals with various …

Identifying Most Significant Predictors Of Low Mathematics Achievement In African American Male Middle School Students, Kelley Adams

Theses and Dissertations

Research has shown that African American males have been singled out due to the fact most local and national data of academic achievement finds the group to underachieve significantly (Garibaldi, 2007). The purpose of this study is to examine variables which significantly predict lower levels of math achievement in regards to African American males. This study also examines variables that predict low math achievement for African American males to determine the most significant of the predictors. This quantitative case study includes sixth, seventh, and eighth grade African American male subjects from a middle school in the Southeast. Socioeconomic status, attendance, …

Graduate Research Papers

The purpose of this research study is to ascertain classroom teachers’ dispositions toward graphic novels as quality literature and the rationale for their beliefs and attitudes. Of particular interest in this study is how teacher dispositions toward graphic novels may differ across teacher age groups. In conducting research, a survey was given to a variety of classroom teachers. These participants are language arts teachers for grades three through eight and range in age from 20 to 60 years. The researcher recorded the frequencies and percentages of responses, looking for teachers’ perceptions of graphic novels, the origin of these perceptions, and …

Improving 21st Century Literacy Skills And Student Engagement By Integrating Digital Storytelling Across The Curriculum, Sandra J. Steinfadt

Graduate Research Papers

The purpose of this literature review is to explore how literacy skills and engagement are increased through the integration of digital story telling into multiple content areas. Thirty peer reviewed articles were analyzed for this peer review. It has been revealed that the use of digital storytelling allows students more creative freedom and increases self-expression and helps students that normally struggle to create written pieces have greater success. Digital storytelling connects classroom content to students' lives, encourages deeper reflection, helps students analyze information and increases their motivation to succeed.

Early Childhood Library Resources And Support, Lisa Catherine Riese

Graduate Research Papers

The increasing demands on teachers' time and the extra strain that small districts face in trying to meet the needs of all students, can mean that sometimes programming or certain groups may be overlooked. In the Colo-Nesco district, realignment of district buildings has caused a loss of library access and resources for the preschool program. This research project created an annotated list of library resources that align with the Iowa Early Learning Standards. Titles were found within the Children's Core database, have been published within the past ten years, and align with the seven content areas of the standards. This …

Tree-Ring Evidence Of North Pacific Volcanically Forced Cooling And Forcing Of The Pacific Decadal Oscillation (Pdo), Lauren Vargo

Senior Independent Study Theses

Two large undocumented volcanic eruptions in 1698/9 and 1809 have been previously identified in ice cores as sulfate peaks, and in tree-ring latewood density data as low-density rings. These eruptions can also be recognized using tree-ring width data, and can be identified in the tree-ring record as narrow rings for several consecutive years. The first part of this study uses tree-ring width data from the Gulf of Alaska to provide further evidence that these eruptions occurred. The two eruptions also provide a natural experiment for investigating the effects large volcanic eruptions have on North Pacific climate, including the Pacific Decadal …

The Truth About Lie Symmetries: Solving Differential Equations With Symmetry Methods, Ruth A. Steinhour

Senior Independent Study Theses

Differential equations are vitally important in numerous scientific fields. Oftentimes, they are quite challenging to solve. This Independent Study examines one method for solving differential equations. Norwegian mathematician Sophus Lie developed this method, which uses groups of symmetries, called Lie groups. These symmetries map one solution curve to another. They can be used to determine a canonical coordinate system for a given differential equation. Writing the differential equation in terms of a different coordinate system can make the equation simpler to solve. This I.S. explores techniques for finding a canonical coordinate system and using it to solve a given differential …

Clustering Methods And Their Applications To Adolescent Healthcare Data, Morgan Mayer-Jochimsen

Scripps Senior Theses

Clustering is a mathematical method of data analysis which identifies trends in data by efficiently separating data into a specified number of clusters so is incredibly useful and widely applicable for questions of interrelatedness of data. Two methods of clustering are considered here. K-means clustering defines clusters in relation to the centroid, or center, of a cluster. Spectral clustering establishes connections between all of the data points to be clustered, then eliminates those connections that link dissimilar points. This is represented as an eigenvector problem where the solution is given by the eigenvectors of the Normalized Graph Laplacian. Spectral clustering …

Hydrogeochemical Analysis For Tasuj Plain Aquifer, Iran, Ata Allah Nadiri, Asghar Asghari Moghaddam, Frank T.C. Tsai, Elham Fijani

Faculty Publications

This study investigated the hydrogeochemical processes of groundwater in the Tasuj plain, Iran. The Tasuj plain is one of the 12 marginal plains around Urmia Lake which is currently under a critical ecological condition. In the last decades, the Tasuj plain aquifer suffered from severe groundwater level declination and caused degradation of groundwater quality. To better understand hydrogeochemical processes in the Tasuj plain, this study adopted graphical methods and multivariate statistical techniques to analyze groundwater samples. A total of 504 groundwater samples was obtained from 34 different locations (qanats, wells, and springs) over 12 years (1997-2009) and analyzed for 15 …

Supervised Committee Machine With Artificial Intelligence For Prediction Of Fluoride Concentration, Ata Allah Nadiri, Elham Fijani, Frank T.C. Tsai, Asghar Asghari Moghaddam

Faculty Publications

The study introduces a supervised committee machine with artificial intelligence (SCMAI) method to predict fluoride in ground water of Maku, Iran. Ground water is the main source of drinking water for the area. Management of fluoride anomaly needs better prediction of fluoride concentration. However, the complex hydrogeological characteristics cause difficulties to accurately predict fluoride concentration in basaltic formation, non-basaltic formation, and mixing zone. SCMAI predicts fluoride by a nonlinear combination of individual AI models through an artificial intelligent system. Factor analysis is used to identify effective fluoride-correlated hydrochemical parameters as input to AI models. Four AI models, Sugeno fuzzy logic, …

Sea Level Rise, Spatially Uneven And Temporally Unsteady: Why The U.S. East Coast, The Global Tide Gauge Record And The Global Altimeter Data Show Different Trends, Tal Ezer

CCPO Publications

Impacts of ocean dynamics on spatial and temporal variations in sea level rise (SLR) along the U.S. East Coast are characterized by empirical mode decomposition analysis and compared with global SLR. The findings show a striking latitudinal SLR pattern. Sea level acceleration consistent with a weakening Gulf Stream is maximum just north of Cape Hatteras and decreasing northward, while SLR driven by multidecadal variations, possibly from climatic variations in subpolar regions, is maximum in the north and decreasing southward. The combined impact of sea level acceleration and multidecadal variations explains why the global mean SLR obtained from similar to 20 …

(P,\\Lambda)-Koszul Algebras And Modules, Ii, Jiafeng Lu

Turkish Journal of Mathematics

This paper is a continuous work of [14], where the notions of (p,\lambda)-Koszul algebra and (p,\lambda)-Koszul module were first introduced. More precisely, some new criteria for a positively graded algebra to be (p,\lambda)-Koszul are provided. We also generalize (p,\lambda)-Koszul objects to the nongraded case and define the so-called quasi-(p,\lambda)-Koszul objects. Further, the relationships between (quasi-) (p,\lambda)-Koszul modules and minimal Horseshoe Lemma are established.

On Some Results On Ip-Graphs, Roghayeh Hafezieh, Moohammadali Iranmanesh

Turkish Journal of Mathematics

The IP-graph of a naturally valenced association scheme and some of its properties have been studied recently. In this paper we introduce the bipartite version of this graph for a naturally valenced association scheme (X,S), denoted by BIP(S). We also investigate some of its properties.

On The Centroid Of Prime Semirings, Hasret Yazarli, Mehmet Ali̇ Öztürk

Variable Appropriation Of An Online Resource Discovery And Sharing Tool, Victor R. Lee, Mimi Recker, Tamara Sumner

Instructional Technology and Learning Sciences Faculty Publications

Even when following best practices for participatory design, the appropriation of tools in formal education settings can be hampered by a number of factors. Drawing from a case of a web tool built to help teachers in five school districts find and share free resources in an educational digital library, we describe patterns of tool use and provide some explanations for variability in tool appropriation. We also suggest that future research consider school districts as complex systems of professionals whose interactions and inter-relationships may yield unexpected technology adoption behaviors.

Picking Up The Mantle Of “Expert”: Assigned Roles, Assertion Of Identity, And Peer Recognition Within A Programming Class, Deborah A. Fields, N. Enyedy

Instructional Technology and Learning Sciences Faculty Publications

Changing an established role in a classroom is difficult. It involves constructing a new set of relations within a community. In this article we investigate how students with newly developed interest and experience in programming developed outside the classroom pick up and establish their roles as experts in programming within the classroom community. More specifically, we focus on how two 11-year-old software designers shifted their established roles in their classroom to gain status as expert programmers. We use an identity lens to understand how peer expertise was established in the context of a classroom community, adopting a multifaceted perspective of …

Role Of 18F-Fdg Pet Scan In Rheumatoid Lung Nodule: Case Report And Review Of The Literature, Christine L. Chhakchhuak, Mehdi Khosravi, Kristine M. Lohr

Internal Medicine Faculty Publications

Flourine-18 fluoro-2-deoxy-glucose (¹⁸F-FDG) positron emission tomography combined with computed tomography (PET/CT) is a useful test for the management of malignant conditions. Inflammatory and infectious processes, however, can cause increased uptake on PET scanning, often causing diagnostic dilemmas. This knowledge is important to the rheumatologist not only because of the inflammatory conditions we treat but also because certain rheumatic diseases impose an increased risk of malignancy either due to the disease itself or as a consequence of medications used to treat the rheumatic diseases. There is an increasing body of evidence investigating the role of PET scans in inflammatory …

Horizon Content Knowledge In The Work Of Teaching: A Focus On Planning, Nick Wasserman, Julianna Connelly Stockton

Mathematics Faculty Publications

Horizon content knowledge, one component of Ball et al.’s mathematical knowledge for teaching framework (e.g., Ball, Thames, & Phelps, 2008), has yet to reach adequate clarity and consensus in the field. Recently, various scholars have worked to further conceptualize and describe the mathematical horizon (e.g., Jakobsen, Thames & Ribeiro, 2013; Figueiras et al., 2011; Zazkis & Mamolo, 2011). In this communication, we identify some limitations in the ways such knowledge has thus far been described and offer an additional form of potential impact of horizon content knowledge on the work of teaching.

The Evolving Role Of Department Chair: Leading Faculty Through Times Of Change, Domenick Pinto

School of Computer Science & Engineering Faculty Publications

How does one manage conflict and change in a very volatile economic climate where academia is experiencing greater accountability, increased emphasis on outcome assessment, declining enrollment and great uncertainty for the future? The role of department chair has, in many cases, become one entrenched in conflict between the role of faculty and administrator and has experienced a tremendous evolution over the last 25 years.

The role of department chair has changed as economic, social and student climates have changed. This paper will summarize collected data from chairs of departments of various sizes and types in order to discuss and understand …

Osler, Langdell, And The Atelier: Three Tales Of Creation In Professional Education, Richard K. Neumann Jr.

Hofstra Law Faculty Scholarship

This article traces the origins of the casebook classroom, the medical school teaching hospital, and the architectural school design studio. These parallel histories show how and why legal education diverged from norms being established in the other two fields. The divergence left legal education stronger within universities than it otherwise might have been. But it also left legal education insulated from its own profession and, to that extent, diminished intellectually.

Uniquely among the professions, law schools use a required curriculum has changed little since 1870. Medical and architecture schools are built around settings where those professions are practiced: teaching hospitals …

Using Gis To Delineate Headwater Stream Origins In The Appalachian Coal-Belt Region Of Kentucky, Jonathan A. Villines

Theses and Dissertations--Biosystems and Agricultural Engineering

Human activity such as surface mining can have substantial impacts on the natural environment. Performing a Cumulative Hydrologic Impact Assessment (CHIA) of such impacts on surface water systems requires knowing the location and extent of these impacted streams. The Jurisdictional Determination (JD) of a stream’s protected status under the Clean Water Act (CWA) involves locating and classifying streams according to their flow regime: ephemeral, intermittent, or perennial. Due to their often remote locations and small size, taking a field inventory of headwater streams for surface mining permit applications or permit reviews is challenging. A means of estimating headwater stream location …

Comparison Of Earthquake Source Models For The 2011 Tohoku Event Using Tsunami Simulations And Near‐Field Observations, Breanyn T. Macinnes, Aditya Riadi Gusman, Randall J. Leveque, Yuichiro Tanioka

All Faculty Scholarship for the College of the Sciences

Selection of the earthquake source used in tsunami models of the 2011 Tohoku event affects the simulated tsunami waveform across the near field. Different earthquake sources, based on inversions of seismic waveforms, tsunami waveforms, and Global Positioning System (GPS) data, give distinguishable patterns of simulated tsunami heights in many locations in Tohoku and at near‐field Deep‐ocean Assessment and Reporting of Tsunamis (DART) buoys. We compared 10 sources proposed by different research groups using the GeoClaw code to simulate the resulting tsunami. Several simulations accurately reproduced observations at simulation sites with high grid resolution. Many earthquake sources produced results within 20% …

Pliocene Sinistral Slip Across The Adobe Hills, Eastern California-Western Nevada: Kinematics Of Fault Slip Transfer Across The Mina Deflection, Sarah Nagorsen-Rinke, Jeffrey Lee, Andrew Calvert

All Faculty Scholarship for the College of the Sciences

The Adobe Hills region (California and Nevada, USA) is a faulted volcanic field located within the western Mina deflection, a right-stepping zone of faults that connects the northern Eastern California shear zone (ECSZ) to the south with the Walker Lane belt (WLB) to the north. New detailed geologic mapping, structural studies, and ⁴⁰Ar/³⁹Ar geochronology in the Adobe Hills allow us to calculate fault slip rates and test predictions for the kinematics of fault slip transfer into the Mina deflection. The Adobe Hills are dominated by Pliocene tuffaceous sandstone, basaltic lavas that yield ⁴⁰Ar/³⁹Ar ages …

Caiden: The Communications System, Jennifer Case

Honors Capstones

CAIDEN is a mobile robotic platform that can be equipped with a number of various sensors for specified use. A communication system was developed to convey commands and data to the robot. XBees were used to obtain wireless communication between the user and the robot. The communication system consisted of both intra- and interrobotic communication. Within the robot, there are a variety of sensors and two micro-controllers that need to work together to make the robot function appropriately. Outside of the robot, there is a GUI that the operator uses to monitor and control CAIDEN's movement. This system was rigorously …

Comparative Analysis Of English Language Learners' Experiences In Public School At The Third And Eighth Grade Levels, Amanda Lenox, Kristin Liewald

Honors Capstones

The field of education is one that endeavors constant change of fluctuating degrees. Most recently and drastically, the educational field has experienced and responded to changes in the cultural and linguistic diversity that is rapidly increasing in classrooms across the United States. Congruently, current legislation holds both educators and students accountable for their standardized performance and accomplishments, although teachers of ethnically diverse students are not required to be certified in the teaching of these learners. As a result, it was the purpose of this study to identify and analyze the themes evident from a series of observations and interviews conducted …
